Advance Product Bulletin Diamond Power Products BG1A Universal High Power IGBT Module Gate Driver Board BG1A-F kit contents: M57160AL gate driver and VLA106-15242 DC/DC converter. BG2A-KA kit contents: VLA504 gate driver and VLA106-15242 DC/DC converter. *The VLA504 replaces the older M57962L gate driver and the VLA106-15242 replaces the M57145L-01 DC/DC converter. Description Features • BG1A is a fully isolated gate drive circuit board designed for use with high current single IGBT modules. When the board is populated, a VLA504 hybrid gate driver supplies the gate drive with complementary emitter follower power booster to provide efficient switching of modules rated up to 1200A. The hybrid gate drivers also provide protection against unexpected short circuit conditions. Isolated control power for the driver is supplied by an onboard VLA106-15242 regulated DC/DC converter. The fault feedback signal is also optically isolated.
